How do I adjust the output voltage range limits on Moku:Pro?
Published April 2nd, 2025 by Laura Becerra
Moku:Pro has two options for output voltage range into 50 Ohms: +/- 1V (2 Vpp) and +/- 5V (10 Vpp). To adjust the output voltage range on the Lock In Amplifier, FIR Filter Builder, PID Controller, Digital Filter Box, and Laser Lock Box, the output gain on the right hand side should be selected and changed to 0 dB for +/- 1V and +14 dB for +/- 5V as
How do I convert dB units from the Frequency Response Analyzer to voltage?
Published March 14th, 2025 by Laura Becerra
The Frequency Response Analyzer calculates gain in decibels (dB) by determining the voltage ratio between the output and input signals. The gain is expressed using the following equation: dB = 20*log10(Vout/Vin)
How can I maintain my output signal in between API calls?
Published March 11th, 2025 by Laura Becerra
Each time the API connects to a Moku device, it resets the outputs. To avoid disruptions in output signals in between API calls, use ‘persist_state’ when claiming ownership of your Moku device. Below is an example of how to implement persist_state: Python: i = WaveformGenerator('xxx.xxx.x.xx', force_connect=True, persist_state=True) MATLAB: i = Moku
Setting up mokucli on Linux with symbolic link
Published February 5th, 2025 by Laura Becerra
To set up mokucli symbolic link on a Linux system: Download the latest mokucli package from the Utilities page . Once the download is complete, get the path for mokucli. Using your terminal, navigate to the inside of the extracted downloads folder. You should see mokucli listed. Type “pwd” in your terminal once inside of the extracted folder to get
Why does the message, "Instrument frame rates may be reduced in this configuration" appear in Multi-Instrument Mode?
Published April 11th, 2025 by Laura Becerra
When using Multi-Instrument Mode (MiM), there are four instruments that can cause the warning “Instrument frame rates may be reduced in this configuration” to appear when placed in one of the instrument slots. The four instruments are the Oscilloscope, Laser Lock Box, Lock-In Amplifier, and Logic Analyzer. These instruments can acquire data at the f
